Referring to fig. 1, fig. 1 is a schematic structural diagram of a polarization structure according to a first embodiment of the present application.
The first embodiment of the present application provides a polarization structure 100, which includes a polarization layer 13, a first protection layer 12, a second protection layer 14, a scattering layer 15, an adhesive layer 11, and a release film 10. The polarizing layer 13 includes a light incident surface 131 and a light emitting surface 132 disposed oppositely. The first protective layer 12 is disposed on the light incident surface 131. The second passivation layer 14 is disposed on the light emitting surface 132. The phase difference of the second protective layer 14 is greater than or equal to 1000 nm. The scattering layer 15 is arranged on the side of the second protective layer 14 remote from the polarizing layer 13. The haze of the scattering layer 15 is greater than or equal to 30%. The adhesive layer 11 and the release film 10 are sequentially disposed on a side of the first protective layer 12 away from the polarizing layer 13.
Therefore, in the polarization structure 100 provided in the first embodiment of the present application, the scattering layer 15 is disposed on the side of the second protection layer 14 away from the polarization layer 13, and the haze of the scattering layer 15 is greater than or equal to 30%, so that when the second protection layer 14 with a phase difference greater than or equal to 1000 nm is used as a protection layer on the light exit side of the polarization structure, if the polarization structure 100 is applied to a liquid crystal display device, the rainbow streak phenomenon can be improved, and the display quality of the liquid crystal display device can be improved.
Specifically, the polarizing layer 13 is a core film layer of the polarizing structure 100, and plays a role of polarization. The material of the polarizing layer 13 may be PVA (Polyvinyl Alcohol).
The first protective layer 12 supports and protects the light incident side of the polarizing layer 13. The material of the first protective layer 12 may be PET (Polyethylene terephthalate), TAC (Tri-cellulose Acetate), COP (Cyclo Olefin Polymer), PC (Polycarbonate), or PMMA (Polymethyl Methacrylate). In the first embodiment of the present application, the first protection layer 12 is a compensation film, and the compensation film can be used for compensating a phase difference of a liquid crystal material inside the liquid crystal display device, so as to improve a contrast ratio or a viewing angle of the liquid crystal display device. The material of the compensation film can be selected according to the actual application requirements, which is not limited in the present application.
The second protective layer 14 protects the light exit side of the polarizing layer 13. The material of the second protective layer 14 may be PET, TAC, COP, PC, or PMMA. In the first embodiment of the present application, the material of the second protective layer 14 is PET.
In the first embodiment of the present application, the phase difference of the second passivation layer 14 is between 1000 nm and 5000 nm.
It can be understood that, in the prior art, since the use of the polarization structure affects the water-proof performance of the liquid crystal display device, in order to improve the water-proof performance of the polarization structure and increase the water-proof performance of the liquid crystal display device, a PET film with a phase difference greater than 8000 nm is generally selected as the protective layer on the light-emitting side of the polarization structure. However, the PET film with a phase difference value greater than 8000 nm has a single source and insufficient productivity, and thus the application of the PET film in a polarizing structure is greatly limited.
For the above technical problems in the prior art, the first embodiment of the present application uses the PET film with the phase difference between 1000 nm and 5000 nm, and the source of the PET film with the phase difference in the above range is wide, so that the rainbow texture phenomenon can be improved, the waterproof effect of the polarized light structure can be improved, and the problem of single supply of the PET film can be solved, thereby expanding the application of the PET film in the polarized light structure.
Specifically, the phase difference of the second protection layer 14 may be 1000 nm, 1500 nm, 2000 nm, 3000 nm, 4000 nm, or 5000 nm, and a specific value of the phase difference of the second protection layer 14 may be selected according to a requirement of an actual application, which is not limited in the present application.
It will be appreciated that in order to further improve or even eliminate the rainbow effect, the smaller the phase difference of the second protective layer 14, the larger the haze value of the scattering layer 15 is generally required. For example, when the phase difference of the second protective layer 14 is 1000 nm, the haze of the scattering layer 15 may be set between 60% and 80%; when the phase difference of the second protective layer 14 is 2000 nm, the haze of the scattering layer 15 may be set between 45% and 60%; when the phase difference of the second protective layer 14 is 3000 nm, the haze of the scattering layer 15 may be set between 35% and 45%; when the phase difference of the second protective layer 14 is 5000 nm, the haze of the scattering layer 15 may be set to 25% to 35%, and so on. The specific correspondence between the phase difference of the second protection layer 14 and the haze of the scattering layer 15 may be set according to an actual situation, that is, on the premise of eliminating the rainbow texture phenomenon, the phase difference of the second protection layer 14 and the haze of the scattering layer 15 may be adjusted according to actual application requirements, and details are not repeated here.
Further, in the first embodiment of the present application, the phase difference of the second passivation layer 14 is between 1000 nm and 3000 nm. The haze of the scattering layer 15 is greater than or equal to 40%.
In the prior art, because the PET film with a phase difference between 1000 nm and 3000 nm has a wide source, it is widely used in the polarization structure. However, the PET film having a retardation in the above range has a small number of peaks of transmitted light in the entire visible light range, and thus the light emitted from the PET film has a poor light mixing effect, and thus the rainbow streak phenomenon is likely to occur.
In the first embodiment of the present application, the second protection layer 14 with a phase difference between 1000 nm and 3000 nm is used, and the scattering layer 15 with a haze greater than or equal to 40% is disposed above the second protection layer 14, so that when the polarized light passing through the second protection layer 14 enters the scattering layer 15, because the scattering layer 15 with a haze greater than or equal to 40% has a large scattering effect on the light, the random degree of the exit angles of the polarized light can be increased, the number of the peak values of the transmitted light of the second protection layer 14 in the whole visible light domain can be increased, and further, after the polarized light with different exit angles exits from the polarized light structure 100, the light mixing effect of the polarized light can be increased, thereby greatly improving or even eliminating the rainbow phenomenon.
Specifically, the inventors of the present application found in a large number of experimental studies that the rainbow effect can be substantially eliminated when the second protective layer 14 having a phase difference of 3000 nm is used and the haze value of the scattering layer 15 is made 40%.
In the first embodiment of the present application, the scattering layer 15 includes the light-transmitting layer 151 and the scattering particles 152 disposed inside the light-transmitting layer 151.
The light-transmitting layer 151 is a glue layer with high light transmittance, and the material of the glue layer may be acrylic resin or epoxy resin. The light-transmitting layer 151 may be formed on the surface of the second protective layer 14 by coating or spraying, or may be directly attached to the second protective layer 14 by a formed film material.
The scattering particles 152 are inorganic nanoparticles, such as silicon dioxide, zirconium dioxide, or titanium dioxide. In the first embodiment of the present application, the scattering particles 152 are silicon dioxide. In some embodiments, the scattering particles 152 may also be other nanoparticles, and the material of the scattering particles 152 is not particularly limited herein. In an actual process, the scattering particles 152 may be doped into the light transmissive layer 151 by means of particle doping, and the doping manner of the scattering particles 152 is not particularly limited in the present application.
By controlling the particle size of the scattering particles 152 and the density and dispersion degree of the scattering particles 152 in the light-transmitting layer 151, the scattering layer 15 having different haze can be obtained. In addition, the haze of the scattering layer 15 can be measured by referring to the prior art, and the description thereof is omitted.
Further, in the first embodiment of the present application, the refractive index of the second protective layer 14 is larger than the refractive index of the light-transmitting layer 151. The specific refractive index of the second protective layer 14 and the light-transmitting layer 151 may be defined according to the selection of the materials of the two, which is not specifically limited in the present application.
When the polarized light penetrating through the second protection layer 14 is emitted to the interface between the second protection layer 14 and the light transmission layer 151, since the refractive index of the second protection layer 14 is greater than that of the light transmission layer 151, the polarized light is refracted after penetrating through the interface, and the incident angle of the polarized light on the interface is smaller than the refraction angle, so that the emergent angle of the polarized light entering the light transmission layer 151 is increased, and the scattering effect of the polarized light is improved.
In the first embodiment of the present application, when the polarizing structure 100 is applied to a liquid crystal display device, the adhesive layer 11 is used to attach the polarizing structure 100 to a liquid crystal cell in the liquid crystal display device. The material of the adhesive layer 11 may be a pressure sensitive adhesive or an optical adhesive. The release film 10 is used to protect the adhesive layer 11 and is torn off when the polarizing structure 100 is attached to a liquid crystal cell.
The polarizing structure 100 provided in the first embodiment of the present application is configured to set the scattering layer 15 on the side of the second protection layer 14 away from the polarizing layer 13, and make the haze of the scattering layer 15 greater than or equal to 30%, so that when the second protection layer 14 with a phase difference greater than or equal to 1000 nm is used as the protection layer on the light exit side of the polarizing structure, if the polarizing structure 100 is applied to a liquid crystal display device, the rainbow streak phenomenon can be improved, and the display quality of the liquid crystal display device can be improved.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a polarization structure according to a second embodiment of the present application. The second embodiment of the present application differs from the first embodiment in that: one surface of the second protective layer 14 adjacent to the scattering layer 15 is a rough surface 141.
This application second embodiment sets up the one side that is close to scattering layer 15 through with second protective layer 14 to rough surface 141, has strengthened the scattering degree of the polarized light of following second protective layer 14 outgoing, and then through the combination with scattering layer 15, can play the effect of further improving or even eliminating the rainbow line.
In the second embodiment of the present application, the second protective layer 14 is surface-treated to form the rough surface 141. Specifically, the second protective layer 14 may be etched, or the second protective layer 14 may be patterned by a mask, and the like, and the method for forming the rough surface 141 is not particularly limited in this application.
Specifically, the rough surface 141 has a concave-convex structure. In the concave-convex structure, the cross-sectional shape of the convex portion in the direction perpendicular to the light exit side of the polarization structure 100 may be a semicircle, a square, a triangle, a trapezoid, or the like, and the specific shape may be set according to the process conditions, which is not described herein again.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a liquid crystal display device according to an embodiment of the present disclosure.
The embodiment of the present application further provides a liquid crystal display device 1000, which includes a liquid crystal cell 200, and a first polarization structure 300 and a second polarization structure 100 disposed on two sides of the liquid crystal cell 200. The first polarization structure 300 is disposed on the light incident side of the liquid crystal cell 200. The second polarization structure 100 is disposed on the light-emitting side of the liquid crystal cell 200. The liquid crystal cell 200 includes a liquid crystal layer 10, and an array substrate 20 and a color film substrate 30 disposed on two sides of the liquid crystal layer 10. The array substrate 20 is located on a side of the liquid crystal layer 10 away from the second polarization structure 100.
